Paper Abstract

In this paper, a new means of measuring the displacement of GMA (Giant Magnetostrictive Actuator) based on FGB (Fiber Bragg Grating) sensor is proposed, experimental results confirmed that FGB sensor can measure the displacement of GMA in different frequencies and achieve good results. In addition a modified Bouc-Wen model is presented to describe the GMA, the proposed model can describe the asymmetric hysteresis of GMA from 1 Hz to 100 Hz well, and DE(Differential Evolution) algorithm is used for adaptive identification of the GMA system, the algorithm has fast convergence and high accuracy. Finally, it verifies that the identification model fits the experimental data well.
